PUMPING DEVICE FOR VELOCIPEDES.

Specification of Letters Patent.

Patented July 20, 1909.

Application filed. February 1, 1909. Serial No. 475,444.

To all whom it may concern:

Be it known that 1, PER GOTTHARD Lans- SON, a subject of the King ofSweden, residing at and whose post-office address is Kristianstad,Sweden, have invented certain new and useful Improvements in PumpingDevices for Velocipedes; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, ref erence being had to the accompanying draw ings, and to figuresof reference marked thereon, which form a part of this specification.

This invention relates to means for attaching tire-inflating pumps tothe axles of vehicle wheels and the object of such invention is toprovide for holding the pump by such means, in operative position whilepumping, without requiring the use of more than one hand or foot in thatoperation.

To this end the said invention consists in the construction andcombination of parts hereinafter more specifically set forth andclaimed.

In the accompanying drawings Figure 1 represents a side elevation of abicycle wheel, to which a plate partly embodying my invention isattached; Fig. 2, a view in front elevation of the same with an air pumpattached; Fig. 3 a detail elevation on a larger scale of the attachingplate and the lower part of the pump looking away from the wheel andFig. 4 re resents on a similar scale a view in detail e evation of theseparts at right angles to Fig. 3, showing more fully the ring and buttonhereinafter described and also showing the rubber tube attached to saidpump.

1 designates the plate which is one of the elements used to attach theair pump 5 to the wheel 12, having the usual pneumatic tire 11 and axle10, also the valve for said tire from which a rubber tube extends to thepump 5. The fork 8 of the bicycle frame is supported 011 said axle. Theparts thus far described have the usual construction and arrangement.

The upper end of the plate 1 is provided with a hole 2, ada ted to iiton the end of the axle protruding eyond said plate, which end receives anut 9, screwed on the same, and the lower part of said plate is bentoutward and again downward so as to be nearly in the vertical plane withthe face of said nut and the end of the shaft and leave room for thebutton hereinafter described without requiring too great an extension ofthe latter toward the wheel, while leaving room for said nut between theplate 1 and pump 5 and preventing any part from getting in the way ofthe other. The lower part of said plate is provided with an opening 4,which is preferably elongated horizontally and has rectangular corners.7 designates a ring clamped around the lower part of said pump andprovided with a projecting button 8 presented rigidly toward the wheel.This button has a narrow neck or stem and an enlarged head, the saidstem being of such size that it may turn in said opening, but the saidhead and opening of such relative size and form that the said-headmaypass through said opening when said pump is in one position but willbe turned across the material of said plate proximate to said slot whensaid pump is turned into another position, so that said button cannotthen be withdrawn through said plate to free said pump from said plateand wheel. The said head as shown has a narrow disk-form resented withits periphery toward the wfieel: but the form of the button and that ofthe slot may obviously be considerably varied, provided the relationsstated be maintained.

To apply the pump, it is held in horizontal position, while the head ofbutton 8 is passed through slot 4 of plate 1, and the said pump is thenturned upright into the position shown in Figs. 2 and 4, bringing thesaid button head across the said slot or o ening 4 as clearly shown inFig. 3. l/Vhile 1n the latter position the operator will need to useonly one hand or foot for steadying it while pumpmg.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In combination, a vehicle wheel having a pneumatic tire and axle, aplate attached to said axle and having an opening and an air pump and abutton attached to said air pum and adapted to pass through said openmg,the said button and opening having such shape that the button head maypass through and be turned across the material of the platesubstantially as set forth.

2. In combination with a ump and a vehicle wheel having an axle, a uttonattached to said pump and a plate attached to the axle of said Wheel andhaving an elongated openand a slot at its lower in combination with aing, the head of said button adapted to be passed through said openingand turned across the same substantially as set forth.

3. A pump, a ring fastened on said pump and a button projecting fromsaid ring, in combination with a vehicle Wheel having a pneumatic tireand axle and a plate attached to said axle and having an opening, thehead of said button being adapted to pass through said opening and turnwith said pump into position for said head to overlap the said platesubstantially as set forth.

4. A plate having a hole at its upper end Wheel axle adapted to passinto said hole, a nut on said axle adapted to fasten said plate thereto,a pump, a ring fastened on said pump and a button on said ring adaptedto pass through the said opening when the pump is horizontal but to turnacross said slot and engage said plate when the pump is turned upright.

5. In combination, a vehicle wheel an axle adapted to engage the slot inthe lower end of said plate.

6. In combination, a vehicle Wheel an axle therefor, a plate having aslot, means for fastening said plate at its upper end to said axle, anair pump and a button fastened to i the lower end thereof and adapted toengage the slot in said plate substantially as set forth.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.

PER GOTTHARD LARSSON.
